inward projections or seats t a at the juncture of the thinner and thicker sections of the T0 all whom, it 711,017/ concern:

Be it known that I, EGBERT MOXHAM, a citizen of the United States, residing at Wilmingbody. Upon one of these projections or seats ton, county of Newcastle, and State of Delais placed the head B and upon the other the ware, haveinvented anew and useful Improvehead B. These heads are also preferably made of pulp, paper, or similar material. The ends b of the body, which are the thinner portions of the body, the portion beyond the seats or projections ct a, are turned over or crimped at c c upon the headsBB', thus clamping the heads securely in place between the crinips c 0 and the internal shoulders L a. C is a bung or stopper also preferably made of pulp, paper, or other similar material in the form of a screw-plug and fitted into the threaded hole in one of the heads. This bung or stopper forms no part of my invention and may be constructed of any material and may be fastened in the head in any other mechanical manner desired. I form this keg by my improved method in the following manner. The machine which I use is shown in Figs. l, 2, and 3. E is the usual vat containing the pulp. F is the mold-roll or pulp-cylinder revolving in bearings in the side wall of the vat. Grisacouchroll revolving in bearings in the side of the vat and contacting with the mold-roll in such a manner as to remove the layers of pulp formed on the mold-roll and transfer them to the winding-roll or mandrel H. The moldroll and the couch-roll have perforations P P, as shown. d 0l d are deckles or closed or non'- perforated portions of the mold-roll. These deckles are well known in the art for the purpose of separating the pulp into sections.

ff f are water-sprays, which receive water from a source of supply. (Not shown.) The mouths of these sprays are each arranged at a distance from the deckles equal to the length of the body, which is to be of thinner crosssection. In carrying out this operation initially the water-sprays are in operation,which not only causes the pulp received upon the roller F to be divided by the deckles into strips, but also prevents the formation of pulp in line with the sprays, which so long as the sprays act form division-lines at these points as well as at the deckles. When the layers have been wound on the winding-roll or mandrel H to the required thickness of the internal projection or shoulder,the water-sprays are shut off. The wet pulp then produces a cylinder wound ment in Processes of Forming Kegs or Vessels Provided with Internal Shoulders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention consists in a method for forming a keg or vessel formed of pulp, paper, or similar material and provided with an internal shoulder upon which the head may be placed and rests.

Speaking generally, my invention consists in forming the body of the vessel of pulp, paper, or similar material in the form of a tube of successive layers of pulp. Impinging picked up to form the tube are water-sprays which wash away or prevent the formation of the pulp at the points of contact of the water with the pulp. After a sufficient number of layers have been formed to equal the thickness of the shoulder desired the water-sprays are stop'ped, and thereafter the pulp winds up in length. I thus form a tube which is provided with a portion or portions partly cut through that may be readily removed, and thus form a shoulder by the different thicknesses of the tube at this point.

In the drawings, Figure 1 is a vertical transverse section in perspective through the body of the tube before the internal collar or portion view of the machine which may be used to carry out my method. Fig. 2 is a vertical transverse section in perspective through the body of the keg made by my improved process. Fig. 2 is a front elevation of the machine of Fig. 1. Fig. 3 is a plan view of my improved keg with the head in place. Fig. 3 is a detail of the water-spray. Fig. i is Aa vertical transverse section of a completed keg or vessel formed by my improved process.

Speaking first of the keg or vessel formed by my process or method which is shown in Figs. 2, 3, and 4, A is the body of the vessel, which is made of layers of pulp in the form of a tube. A portion of this body near each end is on the winding-roll continuous between the removed, so that, as may be seen, the end pordeckles @Zd d d. When the body has reached tions contain less materialand are thinner than the required thickness on the winder H, this the remaining portion of the body.
